Hi,When we ran the load testing for richfaces UI that we developed with minimum load upto 60 users, there was no issue. But if we increase beyond that load, Heap reaches the maximum heap utilization (as configured in jvm settings) and started taking more time for GC (though GC is happening but very limited objects are getting cleared). once the accumulated space reaches the max heap and started throwing OutOfMemory issue. This is only happening in higher user load. When we did the Profiling, we could not figure out this issue since we were able to do profiling with 1 user load.
